Approach to the Musculoskeletal Patient Flashcards
Common musculoskeletal chief complaints include:
- Pain/Stiffness
- Instability/Dysfunction
- Deformity
- Weakness
4 Goals for Evaluating Patients with Musculoskeletal Complaints
- Develop accurate diagnosis
- Provide timely care
- Avoid unnecessary testing
- Identify “red flag” conditions
Keys to Success In Evaluating MSK Complaints
- appropriate, thorough hx
- PE
- DDX - Considering MC disorders first
- Consider need for diagnostic testing
what is often the most important factor in diagnosing musculoskeletal problems
history!
- Obtain a complete ROS
- Thorough past medical history
- Review medications and allergies
- Family history
Key Historical MSK Considerations
LOCATES
- Onset
- Location
- Quality/Character
- Timing/Duration
- Aggravators/relievers
- Associated signs & symptoms
Onset questions when taking hx?
- When?
- Activity at onset?
- Was there an injury?
- What was the MOI? - Timing of onset?
- Sudden vs insidious
location questions when taking hx?
- Joint
- Unilateral vs Bilateral - Bone
- Midshaft
- Joint involvement - Soft tissue
- Muscle, tendon, ligament
Quality/character of pain when taking hx?
- Catching/locking in the joint
- Instability/giving way
- Burning
- Aching vs. sharp
- Radiating
associated s/s of MSK compliant when taking hx?
- Systemic Symptoms
- Neurogenic Symptoms
- Inflammatory Symptoms
MSK/Orthopedic complaints classification
- Traumatic vs. atraumatic
- Articular vs. nonarticular
- Localized/Monoarticular vs. widespread/polyarticular
- Acute vs. chronic
- Inflammatory vs. non-inflammatory
MSK Physical Exam Goals
- Determine structures involved
- Determine the nature of the underlying pathology
- Determine the functional consequences of the process
- Determine the presence of systemic or extraarticular manifestations
Key Physical Exam Principles
- Inspection
- Palpation
- Range of motion
- Neovascular status
- Muscle testing
- Motor and Sensory evaluation
- Special tests
Inspection components of MSK PE
- Expose area of concern
- Have pt point to area of maximal pain/tenderness
- REMEMBER “SEADS” - Swelling, erythema, atrophy, deformity, scars/skin
When examining the extremities, it is IMPERATIVE to examine how?
BILATERALLY
For palpation what are you assessing
- Assess for tenderness, masses, fluctuance, temperature changes, crepitus - Locate point of maximal tenderness
- Imagine the anatomy as you are palpating
- Hard → bone
- Spongy/Boggy → synovial thickening
- Fluctuance → effusion
- Position→ joint or periarticular (bursa)
pain SHOULD NOT discourage you from palpating the affected area
How to assess ROM during MSK exam?
- Provides info on severity and progression of disorder
- Always compare sides!
- Types of ROM:
- Active (AROM)
- Passive (PROM)
- Active Assistive Range of Motion (AAROM) - Measuring ROM
- Can be estimated
- More accurate assessment utilizing a goniometer
Goniometer are preferred for evaluating these specific joints:
- Elbow
- Wrist
- Digits
- Knee
- Ankle
- Great toe
Goniometers are less useful for ___ and ___ ROM evaulation
Hip and shoulder
Overlying soft tissue structures don’t allow for as much precision
how to use a goniometer?
- Start by placing the joint in the “Zero Starting Position”
- In most joints this is in the anatomic position of the extremity in extension - Place the center of the goniometer at the joint
- Have patient actively perform ROM
- Move the distal end of the goniometer to align with the distal extremity
Manual Muscle Testing Grades
- 5/5: Normal (complete ROM against gravity w/full resistance)
- 4/5: Good (complete ROM against gravity w/some resistance) - Sometimes subdivided into 4-, 4, and 4+
- 3/5: Fair (ROM against gravity, but not with resistance)
- 2/5 : Poor (ROM only if gravity eliminated)
- 1/5: Trace (twitch/muscle contraction but no joint motion)
- 0/5: Absent (muscle does not contract)
what is the Neurovascular Assessment
- Assess vascular status in trauma patient
- Assess one muscle/nerve at a time
- Neck and Back - Assess nerve root function
- Extremity - Peripheral nerve testing
- Digits - 2-point discrimination
First line in bone and joint imaging, especially for initial evaluation
Radiography
advantages of Radiography
- fast, inexpensive, readily available, easily interpreted
- Plain x-ray is often needed (by insurance) prior to more detailed imaging
disadvantages of radiography
poor soft tissue contrast, 2D, quality is technician dependent, some radiation exposure (small)
What are used to protect radiation sensitive areas?
Lead shields
Long bone x-rays should be taken how?
include joint above and below
At least 2 planes perpendicular to each other should be obtained
